Jer 51:31

“For thus saith the Lord of hosts, the God of Israel,.... "The Lord of hosts", the Lord God omnipotent, and can do all things; "the God of Israel", and therefore will plead their cause, and take vengeance on Babylon: the daughter of Babylon is like a threshing floor; on which the nations of the earth had been threshed, or punished and destroyed; and now she was like a threshing floor, unto which should be gathered, and on which should be laid, her king, princes, and the people of the land, and be there beat and crushed to pieces. The Targum renders it the congregation of Babylon; and the Septuagint the houses of the king of Babylon; so the Arabic version: it is time to thresh her; not the floor, but the sheaves on it: or, "it is the time to tread her" (u); as corn was trodden out by the oxen; or rather as threshing floors, being new laid with earth, were trodden, and so made hard and even, and by that means prepared for threshing against the harvest; when the corn would be ripe, cut down, and gathered in, and laid up, as follows: yet a little while, and the time of her harvest shall come; when she would be ripe for ruin, and God would, by his instruments, put in the sickle of his wrath, and cut her down, her king, her princes, her cities, and her people; see Rev 14:15. The Targum is, "and yet a very little while, and spoilers shall come to her.'' (u) "tempus calcandi eam", Pagninus, Calvin; "tempus calcare eam", Montanus; "eo tempore quo illa calcari solet", Piscator.”

“(See on Jer 50:24). One post--One courier after another shall announce the capture of the city. The couriers despatched from the walls, where Cyrus enters, shall "meet" those sent by the king. Their confused running to and fro would result from the sudden panic at the entrance of Cyrus into the city, which he had so long besieged ineffectually; the Babylonians had laughed at his attempts and were feasting at the time without fear. taken at one end--which was not known for a long time to the king and his courtiers feasting in the middle of the city; so great was its extent that, when the city was already three days in the enemy's hands, the fact was not known in some parts of the city [ARISTOTLE, Politics, 3.2].”
